Civil construction with a longitudinal rectangular plan covered by a flat roof, in the centre of which a barrel vault that occupies its entire length rises. It consists of a central corridor and a row of sales stalls on each side, and on the outside there are also stops. The stalls are separated by cast iron columns that support the roof. The set stands out especially for its vault, which also serves as ventilation once the stalls are closed. The front façades and the plinth of the building are clad in marble, and the interior of the building is decorated with glazed ceramics with tiles that form stripes of colours that make it more noticeable. The market was designed by the architect from Mataró Emili Cabanyes, and opened on the 5th of June, 1892. A year later, Josep Puig i Cadafalch designed and executed the remodelling of the roof, which gave its current appearance. In 1979, it was restored by the architects Isidre Molsosa and Montserrat Torres. It is a very characteristic building in Mataró which receives the popular name of "the train" due to its elongated shape. For the same reason, it is also popularly known as "the line" or "the tram".

Civil building attached to two side buildings. It consists of a ground floor and two floors. A balcony runs the width of the façade at the height of the first floor. The complex stands out for the use of historicist neogothic decorative elements, as is the case of the crowning of the building – especially the upper windows, which are decorated with profusely ornamented arches with sculpture: arches, floral elements, etc. The façade is covered with high-quality sgraffitos.

Former ‘fideueria’ or pasta and oil shop. "La Confianza", has a modernist decoration and preserves practically all the elements that Puig i Cadafalch designed – tempera on paper, display cases, showcases and oil tanks. On the outside, the tiles and irons that make up the store's name are also preserved. The state of conservation is precarious, especially with regard to the frescoes, which are quite damaged by humidity, and also to the decorative elements of the wardrobes. In the window, some wrought iron that held the baskets of vegetables is missing. Decorative elements It was designed by Puig i Cadafalch in 1896 at the request of the owner, Francesc Palomer. It basically consists of cupboards with showcases, the sideboard, wallpaper on the walls and a plaster frieze. The cabinets and display cases, made of wood with glass doors, were used to display the different types of pasta and semolina. They are elongated vertically with decorations that make them look like little chapels. The sideboard is made of marble, and on the outside there are some forged irons destined for the sacks of legumes. The walls of the store are decorated with wallpaper in three different colours, representing the repeated drawing of a Gothic cross. On the wall, just above the warehouse door, there is a small plaster frieze in the form of a garland, where the owner's name, F. Palomar, and the year 1896 are engraved. Probably from an earlier period are the oil tanks, with a sink and a metal grate. As indicated by a plaster frieze inside, the decoration was carried out in 1896, when it was owned by Francesc Palomer and the designer Josep Puig i Cadafalch. It is currently a grocery store, run by the Pinós family.

The plans of the project are signed by Antoni Maria Gallissà because in 1896 Puig i Cadafalch was no longer the municipal architect because of his bad relationship with the Mataró City Council. The house skillfully combines a wide range of ornamental languages, such as sculpture, glass, sgraffitos and ceramics. The stone is not only used to frame the openings, but serves to incorporate the carvings of the sculptor Arnau, who sculpted two relevant figures: the first one is on the tympanum of the door and represents a girl wearing a spindle, a textile emblem that alludes to the owner's industry, while the second figure is at the foot of one of the arches and is the usual Saint George. The rest of the façade is covered with graffiti, and the tribune stands outs, with Nordic reminiscences. The staggered crowning announces the profile of Barcelona’s Amatller House.

Building that borders the old Red Cross and the old Carmelite convent, now the parish of Sant Josep. It is part of the charity space that will be located in the city at the beginning of the 20th century. The building, owned by the City Council, follows the noucentista style, built in 1912 with modernist elements. The upper windows and the tribune at the entrance are worth noting, which give it a certain similarity with the building next door, by Puig i Cadafalch (Red Cross). Despite everything, the conception of the structure of the house responds to a much more rational, functional and institutionalised line. According to the Heritage Catalogue, where it is included, the façade and the volumes are protected, the interiors being subject to change. Sgrafittos Newly created on the façades, designed and made by the artist Parés de Mataró at the beginning of 1988 on the occasion of the renovation works on the interior and exterior of the building. The sgraffitos occupy approximately 600 m of drawing. When he was entrusted with the project, Parés made 4 preliminary designs, a moderate modernist one, one with flowers, a noucentista one and a simple one. The architect Martí Coll chose the first, the most flowery modernism. The motifs are basically flowers and waves, which can be seen in the borders that surround the building. On the west façade, the coat of arms of Catalonia and the staff of Sant Josep stand out, as the charity still depends on the parish. Like the building attached to the convent, the location of the municipal charity and the old people's asylum was granted to the city council in 1942. The origin of the asylum is due to a provision of the General Captain of the Principality, ordering all the towns to collect all the elderly and poor and give them shelter in 1836. The municipal buildings were insufficient, since there was a primary school for poor girls in the same place, and the current municipal charity of Sant Josep was built in 1912, with an entrance through the wall of Sant Llorenç.

Large enclosure bordered by Prat de la Riba, Herrera and Don Quijote Streets, where three buildings stand out: the tower, the slaughterhouses and the building at the entrance. It is part of the simpler lines that combine the tile, the plaster and the visible work, a style that could be considered late modernism. The set combines blue, green and brown. Recently, works have been carried out for the reuse of one of the warehouses of the slaughterhouse destined for the Municipal Laboratory. Included in the Catalogue of Artistic Heritage of the Mataró town hall, the façades, volumes and interiors are protected. It was built in 1915 on some plots away from the old city walls, since until that time the functions of the slaughterhouse were carried out in the Plaça Gran, in the market. It was the most important work of Melcior de Palau i Simón, "and his project was approved and exhibited to the public in 1911. It was the first slaughterhouse of this style in the peninsula, and it conformed to the norms of hygiene and capacity".
